Installation
Note:
• This unit is for vehicles with a 12-volt battery
and negative grounding. Before installing it in a
recreational vehicle, truck, or bus, check the
battery voltage.
• To avoid shorts in the electrical system, be sure
to disconnect the · battery cable before begin-
ning installation.
• Refer to each product’s manual for details on
connecting the power amp and other units, then
make connections correctly.
• Secure the wiring with cable clamps or adhe-
sive tape. To protect the wiring, wrap adhesive
tape around them where they lie against metal
parts.
• Route and secure all wiring so it cannot touch
any moving parts, such as the gear shift, hand-
brake and seat rails. Do not route wiring in
places that get hot, such as near the heater out-
let. If the insulation of the wiring melts or gets
torn, there is a danger of the wiring short-
circuiting to the vehicle body.
• Don’t pass the yellow lead through a hole into
the engine compartment to connect to the bat-
tery. This will damage the lead insulation and
cause a very dangerous short.
• Do not shorten any leads. If you do, the protec-
tion circuit may fail to work when it should.
• Never feed power to other equipment by cut-
ting the insulation of the power supply lead of
the unit and tapping into the lead. The current
capacity of the lead will be exceeded, causing
overheating.
• When replacing fuse, be sure to use only fuse
of the rating prescribed on the fuse holder.
• If the RCA pin jack on the unit will not be
used, do not remove the caps attached to the
end of the connector.
• To prevent incorrect connection, the input side
of the IP-BUS or optical cable connector is
blue, and the output side is black. Connect the
connectors of the same colors correctly.
• If this unit is installed in a vehicle that does not
have an ACC (accessory) position on the igni-
tion switch, the red lead of the unit should be
connected to a terminal coupled with ignition
switch ON/OFF operations. If this is not done,
the vehicle battery may be drained when you
are away from the vehicle for several hours.
• Cords for this product and those for other
products may be different colors even if
they have the same function. When con-
necting this product to another product,
refer to the supplied Installation manuals
of both products and connect cords that
have the same function.
